FLY SCREEN.

Application filed April 7, 1924. Serial No. 704,793.

T 0 all whom it may concern:

Be it known that I, EDWARD I. IVALLAGE,

- a citizen of the United States, residing at Florence, in the county of Laurendale and State of Alabama, have invented certain new and useful Improvements in a Fly Screen, of which the following is a speclfication.

This invention relates to new and useful improvements'in fly screens and has for its principal object to provide a screen which may be used for doors or windows of buildings or the like, and is so constructed as topermit the escape from the building of the flies or other insects as may be on the inside, and further prevents the return of the flies or insects.

A still further object of the invention is to provide a device of the above mentioned character, wherein a trap is adapted to be associated with the fly screen and communicates with the exit provided therein whereby the flies or insects may be trapped upon leaving the inside of the building in which the screen is supported.

A still further object of the invention is to provide a fly screen of the above mentioned character, which includes a removable trap whereby the insects or flies trapped therein may be exterminated.

A further object is to provide a device of the above mentioned character, which is simple in construction, inexpensive, strong and durable and furthermore adapted for the purposes for which it is designated,

Other objects and advantages of'this" invention will become apparent. during the course of the following description.

In the accompanying drawing'forming a part of this specification, and in which like numerals designate like parts throughout the same: 1

Figure 1 is a front elevational view of my improved. screen with parts broken away.

Figure 2 is a transverse section taken approximately on line 22 of Figure 1.

Figure 8 is a fragmentary sectional View taken on line 3 3 of Figure 1. p v

Figure 4 is a detail fragmentary section of a modification of a fly escape or exit, and

Figure 5 is a further modification with a trap asociated therewith.

In the drawing, wherein for the purpose of illustration is shown the preferred embodiment of my invention, the numeral 1 designates the frame of my improved ,fly

screen, the same beingsubstantially rectan-v gular in design and includes the usual upper and lower cross bars and the side members in the manner as clearly illustrated. .Adapted to be secured to one side of the frame are the upper and lower sectionsQ and 3 respectively which are formed of woven wire fabric, such as is well known in the art, and each of the sections are secured along their marginal edges to the sides and upper and lower cross bars of the frame. The free edges of the woven wire fabric sections are spaced from each other in the manner clearly illustrated in Figure2 ofjthe drawing, and this construction providesia means receiving the fly escape designated generally by the numeral 4.

The fly escape comprises an elongated plate which is formed of any suitable flexible metal such as tin orthe like, and asis clearly illustrated in Figure 20f the drawing, the plate 4 is bent backupon itself as illustrated at 5. The upper edge of the plate t is secured to the lower freeedge of the section 2 of the woven wire fabric and ,the portion adjacent the upper .end of the posed substantially parallel to the sloping portion 6 and the free edge of the upwardly extending portion 10 is secured to the upper free edge of the section 3 in the, manneras clearly illustrated.

The fly escape 4 will thus bear'ranged on the inside of the screen so that the orifices 9 in the curved portion 8 will communicate with the outside of the screen whereby the flies or insects on the inside ()fthe screen will crawl up the section 3 and will pass outwardly through the-orifices and between the sloping portions 6 and 10 and willbe from the inside of the building or house in the window or door of which the screen is supported. 7

If desired, a trap may be placed on the outside of the screen anddisposed over the y 'ftherein 'is 't he ve stibule whiehfcoinprises an elongatedstr p' of'wov'en wire fabric 15, the

Adapted to be removably supported on the Outside of the screen and extending over the fly escape so as to enclose the upwardly ex tending portion 32 is the woven wire fabric housing 37. This housing forms a trap whereby the flies passing outwardly through the openings 33 to the portion 30 of the plate 28 will be caused to pass through the openings 34 in the upwardly extending portion 32 and will be entrapped in the housing between the upstanding portion 32 and the outer portion of the housing. The flies or insects thus captured by the trap may be exterminated by subjecting the same to obnoxious fumes and the insects when exterminated may be removed from the trap by disengaging the trap from its support on the screen. It is to be understood that the housing 37 is provided with end plates similar to the end plates provided with the housing 11 and the supporting means therefor.

It'will thus be seen from the foregoing description, that a fly screen has been provided wherein a fly exit or escape is associated therewith for permitting flies or other insects on the inside of a building to escape and further prevent the return thereof into the building through the screen. The pro vision of a trap in connection with the fly escape will capture and entrap the flies passing outwardly through the fly exit and thus permit the same to be exterminated in a simple and efficient manner.

The simplicityof my device enables the same tobe manufactured at a very low cost stood that various changes in the size, shape and arrangement of parts may be resorted to without departing from the spirit of the invention and the scope of the appended claim.

Having thus described the invention, what I claim is A screen including a' frame, an upper and a lower woven wire fabric section secured thereto, said sections having spaced free edges, a fly escape supported between the edges of said sections, said fly escape including a metallic plate bent back upon itself to provide a folded portion extending alongside of and in spaced relation to the upper portion of the lower section, the ends of said plate being secured to the respective free edges of said sections, a lateral extension formed on the upper portion of the folded portion of the plate and disposed aoljacent the upper edge of the lower section, said lateral extension having an orifice formed therein providing an exit to the outside of the screen, the ends of said plate being spaced to provide an exit communicating with the aforementioned exit.

In testimony whereof I affix my signature. ED'WARD I. VVALLAOE.
